摘　　要：从对变电站核心的智能电子设备(Intelligent Electronic Device,IED)设计的角度出发,运用IEC61850的思想和信息模型,采用面向对象的统一建模语言(Unified Modeling Language,UML)为IED建立了功能、静态对象、动态交互行为等模型,以变压器差动保护为例说明了整个设计过程。针对IEC61850主要采用通信信息片(Piece of Information for Communication,PICOM)描述逻辑节点间的交互,未给出交互时序的不足,采用UML的时序图技术描述保护的交互过程,对IEC61 850的动态建模加以补充和改进,以指导IED运行程序的设计与实现。Starting from the design of intelligent electronic device （lED） that is the core equipment of substation, by use of the idea and information model in IEC61850 and adopting the object oriented unified modeling language （UML） the models for lED such as function, static object and dynamic interaction behavior and so on are established, Taking the transformer differential protection for example, the whole design procedures are illustrated. As IEC61850 only describes the interaction relation among logical nodes with Piece of Information for Communication （PICOM）, and the interactive sequences are not given, the sequence diagram technology of UML is taken to definitely describe the interactive process. This work is an improvement to the dynamic modeling in IEC61850 and it can be used in the design and implementation of monitoring program in IED.
